Abstract

A method and an apparatus for transmitting and receiving broadcasting data in a digital broadcasting system are provided. The method includes analyzing a media transmission characteristic of a moving picture experts group (MPEG) media transport (MMT) package, setting digital video broadcasting generic stream encapsulation (DVB GSE) based on the analyzed media transmission characteristic, and transmitting an MMT packet comprising the broadcasting data constituting the MMT package using the DVB GSE.

Claims

1. A method of transmitting broadcasting data in a digital broadcasting system, the method comprising:

analyzing a media transmission characteristic of a moving picture experts group (MPEG) media transport (MMT) package;

setting digital video broadcasting generic stream encapsulation (DVB GSE) based on the analyzed media transmission characteristic; and

transmitting an MMT packet comprising the broadcasting data constituting the MMT package using the DVB GSE.

2. The method of claim 1, further comprising, when internet protocol (IP) is used, configuring the MMT packet into an IP packet,

wherein the configured IP packet is transmitted through the DVB GSE.

3. The method of claim 1, wherein the transmitting of the MMT packet comprises transmitting signaling information on the DVB GSE through a physical layer.

4. The method of claim 1, wherein the transmitting of the MMT packet comprises configuring the MMT packet into a GSE packet, and the GSE packet comprises an extension header comprising information on the MMT packet.

5. The method of claim 4, wherein the extension header comprises information on a broadcasting channel through which the broadcasting data is transmitted, and information on the MMT package transmitted through the broadcasting channel.

6. An apparatus for transmitting broadcasting data in a digital broadcasting system, the apparatus comprising:

a transmitter configured to transmit the broadcasting data through a network; and

a controller configured to analyze a media transmission characteristic of a moving picture experts group (MPEG) media transport (MMT) package, to set digital video broadcasting generic stream encapsulation (DVB GSE) based on the analyzed media transmission characteristic, and to transmit an MMT packet comprising the broadcasting data constituting the MMT package by using the DVB GSE.

7. The apparatus of claim 6, wherein the controller controls an operation of configuring the MMT packet into an IP packet when an internet protocol (IP) is used, and the configured IP packet is transmitted through the DVB GSE.

8. The apparatus of claim 6, wherein the controller controls an operation of transmitting signaling information on the DVB GSE through a physical layer.

9. The apparatus of claim 6, wherein the controller controls an operation of configuring the MMT packet into a GSE packet, and the GSE packet comprises an extension header comprising information on the MMT packet.

10. The apparatus of claim 9, wherein the extension header comprises information on a broadcasting channel through which the broadcasting data is transmitted, and information on the MMT package transmitted through the broadcasting channel.

11. A method of receiving broadcasting data in a digital broadcasting system, the method comprising:

receiving a generic stream encapsulation (GSE) packet received by using digital video broadcasting (DVB) GSE;

reconfiguring an moving picture experts group (MPEG) media transport (MMT) packet from the GSE packet; and

extracting the broadcasting data from the MMT packet and reconfiguring an MMT package.

12. The method of claim 11, further comprising:

when internet protocol (IP) is used, reconfiguring the GSE packet into an IP packet; and

reconfiguring the MMT packet from the IP packet.

13. The method of claim 11, further comprising receiving signaling information on the DVB GSE through a physical layer.

14. The method of claim 11, wherein the GSE packet includes an extension header comprising information on the MMT packet.

15. The method of claim 14, wherein the extension header comprises information on a broadcasting channel through which the broadcasting data is transmitted, and information on the MMT package transmitted through the broadcasting channel.

16. An apparatus for receiving broadcasting data in a digital broadcasting system, the apparatus comprising:

a receiver configured to receive the broadcasting data through a network; and

a controller configured to control an operation of receiving a generic stream encapsulation (GSE) packet received using digital video broadcasting (DVB) GSE, to reconfigure a moving picture experts group (MPEG) media transport (MMT) packet from the GSE packet, and to extract the broadcasting data from the MMT packet and reconfigure an MMT package.

17. The apparatus of claim 16, wherein the controller controls an operation of reconfiguring the GSE packet into an internet protocol (IP) packet when an IP is used and reconfiguring the MMT packet from the IP packet.

18. The apparatus of claim 16, wherein the controller controls an operation of receiving signaling information on the DVB GSE through a physical layer.

19. The apparatus of claim 16, wherein the GSE packet includes an extension header comprising information on the MMT packet.

20. The apparatus of claim 19, wherein the extension header includes information on a broadcasting channel through which the broadcasting data are transmitted, and information on the MMT package transmitted through the broadcasting channel.
